Abstract

A method for producing at least one wall of a three-dimensional object includes an additive manufacturing process in which at least one manufacturing material is fed in a free-flowing state from at least one feed-in opening of at least one feed-in needle into a supporting material and then cures. The wall extends along a course which comprises a first lateral surface and a second lateral surface opposite the first. The feed-in needle is moved through the supporting material along a printing path, and the printing path corresponds to a path of progression along the course of the wall on which a texturing path is superimposed.

First claim

The invention claimed is:

1 . A method for producing at least one wall of a three-dimensional object, comprising:
performing an additive manufacturing process in which at least one manufacturing material is fed in a free-flowing state from at least one feed-in opening of at least one feed-in needle into a supporting material and then cures, wherein the at least one wall extends along a course of a wall which comprises a first lateral surface and a second lateral surface, wherein the second lateral surface is opposite the first lateral surface, and moving the at least one feed-in needle through the supporting material along a printing path, wherein the printing path corresponds to a path of progression along the course of the wall on which a texturing path is superimposed, wherein the texturing path contains or consists of one or more oscillations which have a wavelength and an amplitude, wherein the wall is made up of layers of the manufacturing material arranged adjacent one another and wherein there is a phase shift of an oscillation of the texturing path between at least a portion of adjacent layers.

2 . The method according to claim 1 , wherein the path of progression extends in a center between the first lateral surface and the second lateral surface.

3 . The method according to claim 1 wherein the oscillation is selected from the group consisting of a sine wave, a triangle wave, and a rectangular wave.

4 . The method according to claim 1 , further comprising varying the wavelength and/or the amplitude over the course of the wall on which the texturing path is superimposed.

5 . The method according to claim 1 wherein the texturing path contains a superposition of multiple oscillations.

6 . The method according to claim 1 wherein the amplitude corresponds at most to a thickness of the wall.

7 . The method according to claim 1 wherein the amplitude corresponds at most to 75% of a thickness of the wall.

8 . The method according to claim 1 wherein the amplitude corresponds at most to 50% of a thickness of the wall.

9 . The method according to claim 1 wherein the phase shift lies between 160° and 200°.

10 . A method for creating a printing path for a method according to claim 1 , comprising:
providing object data of a three-dimensional object which contain information on a course of a wall of the three-dimensional object, providing texturing information which contains information on a desired texturing of a first lateral surface and/or a second lateral surface of the wall, determining a path of progression using the object data and of a texturing path using the texturing information, and creating a printing path by superimposing the path of progression with the texturing path, wherein the wall is made up of one or more layers of the manufacturing material arranged adjacent one another and wherein there is a phase shift of an oscillation of the texturing path between at least a portion of adjacent layers.

11 . The method according to claim 10 wherein the desired texturing contains a logo and/or lettering.

12 . The method according to claim 10 wherein the phase shift lies between 160° and 200°.
